COMPANY, INC., A CORPORATION OF MARYLAND CASE FILLING MACHINE Application filed February 23, 1931.

This invention relates to a machine for filling cases or boxes with cans,cartons, bottles, or the like, and is of the general type of this class of machines disclosed in my United States Patent No. 1,443,157, issued January 23, 1923. 1 a

In the above enumerated patent issued to me, adjusting means are provided for accommodating varying sizes of articles to be packed. In this application improved means are provided for making adjustments for various parts of the machine to accommodate different size packages. to be packed, the object being to simplify the manipulation and adjustment of the machine.

A further object of this invention is to provide an adjustable funnel, thus avoiding a change of the same as different sizes of containers are required. 7

A further object of my invention is the providing of means for simultaneously changing the various loading devices to accommodate different size cans or packages being packed, thus avoiding a rather slow and tedious process of changing singly the various loading devices.

A further object of my invention is the providing of improved means for relatively spacing simultaneously the loading devices.

A further object of my invention is the providing of automatic means for adjusting the plunger head to accommodate the adjustment of the funnel. 1

With the foregoing and other objects in view, my invention consists of the novel construction, combination and arrangement of parts as hereinafter specifically described and illustrated in the accompanying draw ings, wherein is shown the preferred embodiy ment of my invention; but it is understood that changes, variations and modifications can be resorted to which come within the scope'of the claims hereunto appended.

In the drawings of the herein described embodiment of my invention, Figure 1 is a side view in elevation of the machine adjusted for the maximum size of containers or cases, and for the maximum size of cans or packages to be packed; Fig. 2 is a lan view of the machine shown in Fig. 1; ig.

Serial No. 517,644.

3 is an end view taken in end elevationlooking in the direction of the arrow 3, in Figs. 1 0nd 2; Fig. 4 is a View, partly in section, in elevation similar to the view shownin Fig. 3, but taken through section 1+4: of Figs. 1 and 2; Fig. 5 is an enlarged viewin elevation of the portion of the'main housing 5211161637 carrylng the markings to accommo-' date the adjustment ofsupporting member 38; Fig. 6 is an enlarged view of the endof loading floor 32, showing particularly the connection of fulcrumed runway members 47 on the respective sides of the machine, Fig. 7 being a side view in elevation of that shown in Fig. 6; loading floor 311s similarly connected to fulcrum runway members 46. 7

Similar numerals refer to similar parts throughout the several views.

1 is the bottom rail; there are two shown, one on each side of the machine, and form the base of the machine. 2 are the legs which are secured to-bottomrail 1, said legs being extensibly adjustable in order, that the machine may have the desired angle with reference to the horizontal, and concerning which I claim nothing in this application. 3 is a header, slidably mounted on bottom rail 1.

tween dog 7 and header 3 upon the setting up of clamping screw 8.

In header 3 are supporting members 9, 10 and 11 operating on one side over guide 12 formed on header 3, and on the other side by means of support 13 and nuts 14 and 15 formed thereon, and are supported thereby and in which support 13 screw 16 is secured and in which nuts 14 and 15 screws 17 and 18 operate, the latter. screws being formed integral with the shaft 19, which shaft is j ournalled at the bottom into lug 3 on'header 3. In the lower end of shaft19 is a hole which is threaded and in which screw 16 operates, V

and at the top shaft 19 is j ournalled in bearing 21 in header 3, and its weight is taken by collar 22 which is secured to shaft 19 by pin 23. On each of supporting members 9 and 10 are secured butting end members 25 and 26, end butting member 24 being permanently secured to header 3. These members 0perate against guide 11 on the opposite side from supporting members 8 and 9', as mentioned above.

28 is the funnel side spacing member secured to header 3, and has integral therewith funnel bottom member 29. 30, 31 and 32 are loading floors upon which cans, if cans are being packed, roll prior to packing. These floors are inserted under end butting members 24, 25 and 26. End member 33 has secured to it and carries top funnel arm 27, and is itself secured to supporting member 11. Loading floor is secured to header 3; loading floors 31 and 32 rest on supporting members 9 and 10 and are carried thereby.

These floors are provided with flanges on the rear and are brought to sharp edges on the front edge, or edgenearest the container.

End butting members are also brought to a sharp edge on the front and are in alignment with side spacing member 28.

34 is the funnel side spacing member to which is attached funnel bottom member 35. These two members are relatively stationary and are secured to main housing 36. In main housing 36 is guide 37 in which operates supporting member 38; this member having a slot therein 39 for adjustment purposes and is secured in said guide by bolt 40. Supporting member 38 is attached thereto and carries top case guide 41, this arm being adj ustable vertically to accommodate theadjustment of top case guide 27 to accommodate the height of containers to be used.

Main housing guide 37 is provided with {suitable markings on its face, and a pointer 42 is secured to supporting member 38 to indicate the size of the container used. Likewise, end member 33 has a mark registering wlth markings on header 3, shown as markings 43.

and 47, respectively.

52 is hand adjusting lever fulcrumed to main housing 36 at 53, and hasfulcrumed to it links 48 and 49 at 54 and 55, respectively; the other, end of said links being pivotally connected to fulcrumed runway members 46 I and 47, respectively, and positioned so that upon the operation of said lever 52 the respective desired spacings may be had between the respective loading floors 30, 31 and 32. Loading floors 31 and 32 are carried by runway members 46 and 47, respectively, on one side, the side nearest the funnel, by being inserted within said members as shown at 56 and 57. (See F ig. 6.) Links 49 are extended downward and operate against bottom rail 1, and are provided with pin 58 going through the same and resting on top of bottom rail 1 when in adjusted position, said links being provided with a series of holes for this adjustment, said pin being provided with a head to lock over bottom rail 1 to prevent its withdrawal by the jarring of the machine in operation.

Between bottom'runway and carriers and 51 are stop appliances 59 and 60 and 61 for stopping the supply of cans when the plunger is operating to fill the container; appliances 60 and 61 being fulcrumed at 66 and 67, respectively, on fulcrum runway members 46 and 47, respectively. These members are tilting members and are operated by link 68 having a relative longitudinal movement caused by the operating device 69 pull- C90 ing same up or down by mechanism not shown, link 68 being mounted on links 70 and 71. The adjustment of various floors being had through slots 72 and 73 in said links. Two of these stop appliances, 60 and 61, however, are carried'for means of adjustment by fulcrumed runway members 46 and 47.

62 are the plunger rods carrying adjustable plunger heads 63. and operate transversely to'the feeding of the articles on the (100 loading floors 30, 31 and 32 for pushing the same therefrom into the container. In plunger head 63 is telescoped adjustable extensions 64 heldout in maximum position by springs 65, these extensions butting against 1 end butting members 24, 25 and 26, and accommodate themselves to adjustment of header 3 on bottom rail 1. As I claim nothing concerning the mechanism foroperating the plunger as such, I will not further describe the same; the adjustable head, however, being a feature of this invention.

In sorting head 44 is adjusting member 74 operating at one end by a sliding fulcrum 75 in sorting head 44 in slots 76 and held in position by pin 77 operating through holes 78 in adjusting member 74, and in holes 79 in sorting member 44, there being a number of such holes for adjustment. This permits v said adjusting member to be tilted to accommodate the various size cans to enter between adjusting member 74 and stop members 80 fixed on fulcrum member 47.

81 is thecontainer carrier adjustable with reference to bottom rail 1 by means of bracket 82, against which it is secured and adjustable therewith by means of slot-83 and bolt 84.

The operation of my invention is as fol lows: V

Y The size of the container being determined 'tainer reasonably snug.

upon, header 3 is adjusted on bottom rail 1 to fit funnel side spacing member 28 and funnel side spacing member 34 within thecon- Bottom funnel members 29 and 35 being within the container on the bottom, top funnel arms 27 and 41 are then raised as follows: Topufunnel arm 27 is raised by means of revolving shaft 19 by means of pin 23, whereby screw 18 raises nut 15. Top funnel member ll is raised by slacking bolt and raising supporting member 38 until the top funnel arms 41 and 27 correspond in height and fit within the container when in position. Hand adjustinglever 52 adjusts loading floors 31 and 32 with reference to loading floor 30 and with reference to each other, according to the size case to be packed, determined by the openings or holes in link 49 held in place by pin 58.

Adjusting member 74 is adjusted to per.- mit the correct size case to pass between it and stop 80. The adjustable plunger head and adjustable plunger extension 63 and 64 take care of the varying size of the container caused by the adjustments of header 3. In these specifications and claims, when I use the term, packages, cans, "or articles to be packed, I mean such articles as by their nature are adapted to being packed by th s machine, such as, roundcans, round bottles, round cartons, or any other round article.
